Achatinella (^Achalinellastrzmt) cuneus Pfeiffer, P. Zool. Soc. London, 1855, 

 p. 205. 



Newcomb considered this a form of A. decipiens; Dr Hartman appears to have 

 been in some confusion, as he placed it (P. Ac. Philad. 1888) at p. 29 under A. decipiens, 

 and at p. 30 under A. viridans. I have seen a long and characteristic series found on 

 the Island of Oahu by Mr Hutchison. 



Hab. Oahu (authors) ; Halawa (Baldwin) ; mountains behind Ewa (Perkins). 



(83) Achatinella [Achatinellastrum) curta Newc. 



Achatinella airta Newcomb, P. Zool. Soc. London, 1853, p. 144, pi. xxiii. fig. 43. 

 Achatinella Jindiilata Newcomb, P. Boston Soc. v. (1855), p. 219; Amer. J. 



Conch. II. (1866), p. 216, pi. XIII. fig. 15; Pfeiffer, P. Zool. Soc. London, 



1855, p. 208. 

 Achatinella dimorpha Gulick, Ann. Lye. New York, vi. p. 236, pi. viii. fig. 56. 

 . Achatinella albescens Gulick, t. c. p. 237, pi. viii. fig. 57. 

 Achatinella contracta Gulick, t. c. p. 239, pi. viii. fig. 59. 

 Achatinella rhodoraphe Smith, P. Zool. Soc. London, 1873, p. 75, pi. ix. fig. 10; 



Gwatkin, P. Ac. Philad. 1895, p. 238 [radula]. 

 Achatinella pyg-ntcea Smith, P. Zool. Soc. London, 1873, p. 75, pi. ix. fig. 11. 



• Hab. Oahu, Waialua (Newcomb); various localities (Gulick); Halemano, 

 Waipio, &c. (Smith) ; between Kawailoa and Waala gulches, generally between 

 Kawailoa and Halemano, Waimea (Perkins). 



(84) Achatinella {Achatitiellastrtim) delta Gulick. 



Achatinella delta Gulick, Ann. Lye. New York, vi. p. 231, pi. viii. fig, 50. 

 Newcomb considered A. delta to be a more banded variety of A. airta Newc. ; 

 from the material I have seen I incline, with doubt, to leave them distinct. 

 Hab. Oahu, Kalaikoa, Halemano, &c. (Gulick). 



(85) Achatinella {Achatincllastritm) diluta Smith. 



Achatinella dilnta Smith, P. Zool. Soc. London, 1873, p. 75, pi. ix. fig. 14. 

 It is near to, but seems distinct from, A. ligata Smith, with which Dr Hartman 

 placed it. 



Hab. Oahu, probably (Smith).
